The perimeter of a football field is 920 feet. The width is 60 feet more than one-third of the length. What are the dimensions of a football field?
Given:
Perimeter of a football field = 920 feet.
The width is 60 feet more than one-third of the length.
To find:
The dimensions of a football field.
Solution:
Let the length of the field be x.
Then, width = [tex]\dfrac{1}{3}x+60[/tex]
We know that,
[tex]Perimeter = 2( length + width)[/tex]
[tex]920 = 2(x+\dfrac{1}{3}x+60)[/tex]
[tex]920 = 2(\dfrac{4}{3}x+60)[/tex]
[tex]920 =\dfrac{8}{3}x+120[/tex]
Subtract both sides by 120.
[tex]920-120 =\dfrac{8}{3}x+120-120[/tex]
[tex]800 =\dfrac{8}{3}x[/tex]
Multiply both sides by 3.
[tex]2400 =8x[/tex]
Divide both sides by 8.
[tex]300 =x[/tex]
Now,
[tex]Length = 300\text{ feet}[/tex]
[tex]Width=\dfrac{1}{3}(300)+60[/tex]
[tex]Width=100+60[/tex]
[tex]Width=160\text{ feet}[/tex]
Therefore, the length and width of the football field are 300 feet and 160 feet respectively.

Stan has $95. He wants to buy as many movies as he can. All movies are originally
$12.00 and are on sale for 10% off. Tax is 5%
Answer:
Step-by-step explanation:
Each movie is $12.00. 10% off of 12% is 12-1.2 = 10.8
The final amount spent is 5%, that means we can multiply the end amount spend by 1.05
The maximum Stan can spend is $95
[tex](10.8m)*1.05\leq 95\\(10.8m)\leq 90.4762\\m \leq \frac{90.4762}{10.8}\\m\leq 8.3774[/tex]
Now, you can't buy 0.3 of a movie, so the most Stan can buy is 8 movies

Answer:
An equilateral triangle is one with all three sides the same length. It begins with a given line segment which is the length of each side of the desired equilateral triangle. ... It is similar to the 60 degree angle construction, because the interior angles of an equilateral triangle are all 60 degrees.

Just one simple question
Answer:
i) OC=a+b
ii) BA=a-b
iii)CA=-b
Step-by-step explanation:
i) because it is a parallelogram AC=OB and therefore AC=b
to find OC you do OA+AC which is a+b
OC=a+b
ii) to find BA you do BO+OA
BO=-b as it is the opposite direction
OA=a
so therefore BA=a-b
iii)CA is the opposite of AC which was b so CA=-b
Shen runs each lap in 5 minutes. He will run at most 45 minutes today. What are the possible numbers of laps he will run today? Use n for the number of laps he will run today.
Answer: The possible numbers of laps he will run today = 9
Step-by-step explanation:
Let [tex]n[/tex] = number of laps he will run today.
Given: Time taken for each lap = 5 minutes
Time taken for [tex]n[/tex] laps =[tex]5n[/tex] minutes
If he runs at most 45 minutes, then
[tex]5n\leq45[/tex]
Divide both sides by 5 , we get
[tex]n\leq9[/tex]
Hence, the possible numbers of laps he will run today = 9

7 freshmen, 9 sophomores, 8 juniors, and 8 seniors are eligible to be on a committee. In how many ways can a dance committee of 14 students be chosen? In how many ways can a dance committee be chosen if it is to consist of 2 freshmen, 3 sophomores, 4 juniors, and 5 seniors.
Answer:
[tex]Number\ of\ Committee = 6914880\ ways[/tex]
Step-by-step explanation:
Given
Total:
[tex]Freshmen= 7\\ Sophomores = 8\\ Juniors = 8\\ Seniors = 8[/tex]
Selection
[tex]Freshmen= 2\\ Sophomores = 3\\ Juniors = 4\\ Seniors = 5[/tex]
Required
Determine the number of selection
To do this, we make use of combination formula:
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
For Freshmen, we have:
[tex]n = 7; r = 2[/tex]
[tex]^7C_2 = \frac{7!}{(7-2)!2!}[/tex]
[tex]^7C_2 = \frac{7!}{5!2!}[/tex]
[tex]^7C_2 = \frac{7 * 6 * 5!}{5! * 2 * 1}[/tex]
[tex]^7C_2 = \frac{7 * 6}{2}[/tex]
[tex]^7C_2 = \frac{42}{2}[/tex]
[tex]^7C_2 = 21[/tex]
For Sophomores, we have:
[tex]n =9;r=3[/tex]
[tex]^9C_3 = \frac{9!}{(9-3)!3!}[/tex]
[tex]^9C_3 = \frac{9!}{6!3!}[/tex]
[tex]^9C_3 = \frac{9 * 8 * 7 * 6!}{6! * 3 * 2 * 1}[/tex]
[tex]^9C_3 = \frac{9 * 8 * 7 }{6}[/tex]
[tex]^9C_3 = \frac{504}{6}[/tex]
[tex]^9C_3 = 84[/tex]
For Juniors, we have:
[tex]n = 8; r = 4[/tex]
[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]
[tex]^8C_4 = \frac{8!}{4!4!}[/tex]
[tex]^8C_4 = \frac{8 * 7 *6 * 5 * 4!}{4!*4 * 3 * 2 * 1}[/tex]
[tex]^8C_4 = \frac{8 * 7 *6 * 5}{4 * 3 * 2 * 1}[/tex]
[tex]^8C_4 = \frac{1680}{24}[/tex]
[tex]^8C_4 = 70[/tex]
For Seniors
[tex]n = 8; r = 5[/tex]
[tex]^8C_5 = \frac{8!}{(8-5)!5!}[/tex]
[tex]^8C_5 = \frac{8!}{3!5!}[/tex]
[tex]^8C_5 = \frac{8 * 7 *6 * 5!}{5! * 3 * 2 * 1}[/tex]
[tex]^8C_5 = \frac{8 * 7 *6}{3 * 2 * 1}[/tex]
[tex]^8C_5 = \frac{8 * 7}{1}[/tex]
[tex]^8C_5 = 56[/tex]
[tex]Number\ of\ Committee = Freshmen\ and\ Sophomores\ and\ Juniors\ and\ Seniors[/tex]
and implies *, so we have:
[tex]Number\ of\ Committee = 21 * 84 * 70 * 56[/tex]
[tex]Number\ of\ Committee = 6914880\ ways[/tex]

Answer:
The measurement of largest angle is 83°
Step-by-step explanation:
Given angles are:
(2x+1)° , (x+15)° and x°
The sum of internal angles of a triangle is 180°
We will use this sum to find the value of x first
[tex](2x+1)+(x+15)+x = 180\\2x+1+x+15+x = 180\\4x+16 = 180\\4x = 180-16\\4x = 164\\\frac{4x}{4} = \frac{164}{4}\\x = 41[/tex]
Now the measurement of angles are:
x = 41
[tex]2x+1 = 2(41)+1 = 82+1 =83\\x+15 = 41+15 = 56[/tex]
Hence,
The measurement of largest angle is 83°

Solve for x. 4x-5=9+20
Answer:
x = 8.5
Step-by-step explanation:
4x-5=9+20 (evaluate right side)

Step-by-step explanation:
We require to create 2 equations with the repeating value placed after the decimal point.
let
x = 1.3333... → (1) ( multiply both sides by 10 )
10x = 13.3333... → (2)
Subtract (1) from (2), eliminating the repeating decimal

the angles measures
Pls help asap
Answer:
The difference between the angle measure is 152 degrees
Step-by-step explanation:
Supplementary angles are angles that add up to 180
So if one angle is x in this case, the other will be 14x
Adding both ;
x + 14x = 180
15x = 180
x = 180/15
x = 12
The other angle is 14 * 12 = 168
The difference between the two will be;

Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 per year. She will also spend about $100 a month commuting from her parents’ house to school. How much will her education cost her in total?
Answer:
$13,400
Step-by-step explanation:
Given the following data;
Tuition and book per year = $5,500
Transportation per month = $100
In 2 years;
Total tuition and book = $5,500 * 2 = $11,000
Total tuition and book cost = $11,000
Transportation;
There are 12 months in a year, in 2 years = 12 * 2 = 24 months.
Thus, total on transportation = $100 * 24 = $2,400
Total transportation cost = $2,400
[tex] Overall \; cost = Total \; tuition \; and \; book \; cost + Total \; transportation \; cost[/tex]
Substituting into the above equation, we have;
Overall cost = $11,000 + $2,400
Overall cost = $13,400.
Hence, Lakita's education will cost her $13,400 in total.
Solve the equation.
y + 6 = -3y + 26
Oy= -8
O y = -5
O y = 5
Oy = 8
The solution to the equation is y = 5.
Therefore, the correct answer is "O y = 5."
Option C.
Here,
Let's solve the equation step by step to find the value of y:
Combine the y terms on the left side of the equation:
y + 3y + 6 = 26
Combine the y terms on the left side of the equation:
4y + 6 = 26
Move the constant term to the other side of the equation:
4y = 26 - 6
Simplify the right side:
4y = 20
Now, solve for y by dividing both sides of the equation by 4:
y = 20 / 4
y = 5
So, the solution to the equation is y = 5.
Therefore, the correct answer is "O y = 5."
Option C.
